Order Onion Allergy Test | Food AllergiesOnion is a common culinary ingredient, yet it is not among the foods most frequently associated with allergic reactions. When symptoms appear after eating onion, an immune response involving immunoglobulin E, or IgE, may be responsible. The Onion Allergy Screen measures IgE antibodies specific to onion in a blood sample, providing an objective result that can help clarify whether an allergy is present.
About Onion Allergy Test | Food Allergies in Farmington
The Onion Allergy Screen is a blood test that detects IgE antibodies directed against onion proteins.
IgE antibodies are produced by the immune system when it identifies a substance as a threat. In a true food allergy, these antibodies bind to proteins in the food and trigger the release of chemicals such as histamine, which cause symptoms that may include hives, itching, swelling, stomach upset, or difficulty breathing.
The test uses a blood sample to measure the level of onion-specific IgE. Because it relies on a blood draw rather than exposure to the food, the test does not itself provoke an allergic reaction. Results are reported as a numeric value that indicates whether sensitization to onion is present.
A positive result shows that IgE antibodies to onion were detected, but it does not by itself confirm that eating onion will cause symptoms. Sensitization can occur without clinical allergy, and some individuals may have symptoms that are not IgE-mediated. A physician interprets the result alongside the patient's history and other findings.
